Patent EP-0306817-A2 (EP)
Inventor: YATSUGI TOMISHIGE
IPC: G11B5/024
Filed: 1988-08-31
Abstract: The present invention relates to a drive circuit for a rotating erase head (1) used in magnetic recording and reproducing apparatus of rotating head type. Resonance capacitance (8) is added in parallel across terminals (4, 4) of a stationary winding of a rotating transformer (3) for transferring an erase signal to said rotating erase head (1). The resonance capacitance (8) causes parallel resonance at an erase signal frequency (fe) in conjunction with an inductance component (Lr) obtained when the rotating erase head (1) is seen through the rotating transformer (3). Since a parallel resonance current (i r ) thus flows through the rotating erase head (1), a very large erase current (i e ) as compared with a drive current (i d ) supplied by a drive circuit (6) can be obtained. Since the resonance capacitance (8) can be disposed within the drive circuit (6), it can be mounted very simply and the space can be efficiently used. In addition, there is no cost up of a rotating cylinder (2) on which the rotat­ing erase head (1) is disposed at all.

In a surface acoustic wave device having a c-axis-oriented aluminum nitride film, the direction of c-axis orientation of the piezoelectric film is inclined within a plane containing the direction of propagation of the surface acoustic wave and perpendicular to the surface of the piezoelectric film at an angle in the range of about ±30 degrees to about ±150 degrees with respect to a normal to the piezoelectric film. The devices are 1.122% in maximum coupling coefficient.

Abstract: An on-board self diagnostic capability is realized in a circuit board with a microprocessor (20) which is located on the circuit board and which interacts for diagnostic purposes with the functional circuitry (10) on the board. The microprocessor interacts with an electrically erasable read-only-memory (EEROM) (30) that is also located on the circuit board. Diagnostic signals (14) occurring during the circuit board's normal operation are automatically detected and stored in the EEROM. Additionally, a control port (105) at the circuit board permits activation in the microprocessor of diagnostic routines that accept input test data (104), apply test sequences to the functional circuitry and store the diagnostic results in the EEROM. Also, through control of the microprocessor, the EEROM is accessed to retrieve previously stored diagnostic results (103).

Abstract: An automobile telephone device uses as its power source a battery (3) for the automobile. This applies to an automobile telephone device with an automatic answering or receiving function. In the automobile telephone device, a voltage monitoring unit (16) monitors the voltage of the battery (3). When the voltage falls near a limit voltage required for starting the automobile engine, the monitoring unit electrically interrupts a power source line (18) connecting the battery and the telephone device via a proper switch circuit (17) to thereby inhibit excessive consumption of the automobile battery by the automatic answering or receiving function during engine stoppage.

Abstract: The invention comprises a frequency converter for converting an input frequency to an output frequency where the frequencies are widely separated. The system includes a free running output oscillator (30) adapted to be injection locked to an output frequency. A local oscillator (20) having a frequency near the output frequency, has its signal mixed with the input frequency to obtain a signal containing sideband frequencies which are both above and below the local oscillator frequency. Means (11 and 26) are provided for separating the sideband frequencies and applying one of the sidebands as an injection locking signal to the free running oscillator (30). In the preferred embodiment, the bandwidth of the free running output oscillator is centered above the highest sideband frequency if the sideband is lower in frequency than the frequency of the local oscillator or is centered below the lowest sideband frequency if the sideband is higher in frequency than the frequency of the local oscillator.

Abstract: Using the voltage-to-frequency conversion method and a device for implementing the method, an extremely fast and highly accurate digitisation of an analog input signal (UE) with a high degree of frequency deviation can be achieved by simple means. An input voltage(U@) raised into the positive range is integrated and compared as integrated voltage (UJ) with a reference voltage (UA) which can be varied in equidistant steps. If the integrated voltage (UJ) is greater than the reference voltage (UA), a logical "1" binary signal is generated, if it is smaller, a logical "0" binary signal is produced. This produces a pulse repetition rate which is proportional to the input voltage (UE). The reference voltage (UA) is incremented with each pulse (P) so that it follows the integrated voltage (UJ) in stairstep manner.
